On the vertical posts 1 at the longitudinal andtransverse rods adjustably opposite end are also sockets 2O in which a attached to the said frame,'attachments on frame 21 is adjustably and pivotally held a5 the said rods and suitable means forraising which may be moved upward or downward or lowering the said rectangular shaped with the lower bar adaptable to move outframe, j ward to rest uponthe rectangular frame 3 to Other features and advantages of the inform a head or back rest at any suitableinvention will appear from the following declination. On the posts at' this end are also 9o scription, taken in connection with the drawhinged sockets 22 that form bearings for a ings, wherein: j square'transverse shaft 23 uponwhieh drums Figure l is a view showing the bed as it 24 may be mounted and which may lalso be would appear ready for use. supplied with a ratchet 25 and a pawl 26 to Figure 2 isa detail taken on line 2-2 of engage the ratchet and hold the drum in any 95 Figure 1 with the corner post omitted and suitable position. The outer end of the shaft showing the arrangement of the ratchet and 23 may be provided'withv a crank 27 by which drum and the attachment for holding them it may readily be rotated. At theupper to the post. ends of the posts 1 at this end are also con;

Figure 3 is a detail showing means for atnections 9 which hold the ends of the rods 2 100 taching the adjustable frame to a .bed by and also a transverse rod 28 thatis similar clamping the legs together. to the rod 8 at the opposite end. Adjustable Figure 4 is a detail showing means for sockets 29 with pulleys 30 suspended. from placing the frame on a bed having corner them are slidably mounted on the shaft28 posts by cutting off the topsof the post and and these cooperate with similar sockets on aplacing a socket over them. the rod 8 and the drums 24`to operate blocks In the drawings the device 'is shown as it 30 through cords as shown. It will be obwould be made, wherein numeral indicates @W92 that the blQl .29 are' provlded wlth hooks for gripping the frame 3 so that the frame may readily be raised or lowered by turning the crank 27.

Sockets 31 are slidably mounted on the bars Sand 28 and support a central longitudinal bar 32 upon which smaller transverse bars 33 areslidably mounted through sockets 34. Some of these bars are provided with slidable sockets 35 having pulleys 36 suspended from them for raising and stretching arms or the like and some of these bars are provided with slidablesockets 37 may then be attached to the having swivel sockets 38 attached to them in which another bar 39 may be sli'dably held and other sockets 35 may be slidably mounted upon this bar so that it will be possible to; grip and hold any part of the body in any suitable position.-

The rectangular frame 3 may be made of any suitable material, which may also be of any suitable shape and may be provided with members 40 4that are pivotally attached to clamps 41 by pins 42 as shown. It will be observed that the clamps 41 may be firmly clamped aroundthe posts l by screws 43 and the pins 42 may be loosened when it is desired to raise the frame so that the frame may bey adjusted to anysuitable angle. It will be observedthat either end of the frame may be raised, as shown by the dottedv lines.

The super frame which rests upon the posts l may be placed over a bed and the frame 3 and the head rest 21 may be omitted. The super frame may readily be adjusted to theI length and width of the bed and the post-s 1 held to the posts of a bed, which are indicated by the numeral 44 by clamps 45 which have hinged inner members 46 to lit any sized post.

It is also understood that the upper portion of the frame only may be used in combination with a bed having vertical corner posts and the corner posts, which are ind-if cated by the numeral 46 and shown in Fig-- ure 4 may be cut off. A socket 47 may then be provided which has a threaded shank 48 that screws into the portion 5 of the connection 4 and is provided with an opening in the lower end which may be placed over the upper ends of the posts 46. The bar 13 and the members at the opposite end of the frame bed posts if desired.l

It will be understood that changes may be made in: the construction without departing from the spirit of the invention, one of which changes may be in the use of material of any other shape, another may be in the combination or arrangement ofl any of the parts and still another may be in the use of connections of any other suitable designs.

The construction will be readily understood from the foregoing description.` To use the device it may be assembled as shown with the rod 13 extending to either side and the rods 33 also extending in either direction. It will be observed that by arranging these parts in anysuitable manner it will be possible to hold or stretch any portion of th body.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:
